Author Topic: 5698 Stacking (Read 612 times)

Hi all,

Quick question, when stacking ERS5698 PWR’s, do the same rules apply as other 5000 series? As in a maximum of 8 units are stackable? Reading NN47200-300_04.06_Installation.pdf it says

“You can connect up to 8 5600 Series devices in a stack to provide uninterrupted connectivity
for up to 384 ports. Bandwidth in a 5600 Series stack is 144 Gbps.”

Using 8x 5698’s will give 768 Ports, would this stack be acceptable or would it need to be split and have two 4x 5698 stacks to have 384 ports per stack?

Thanks for your help.

Andy

Avaya recommends that the number of ports does not exceed 400 ports. (page 28 of NN47200-500 - Configuration System)

Hi Andy,

That's a great question... not sure of the technical answer but as Jon mentions above there was a limitation of ~ 384 ports per switch/stack. Also from a management perspective you definitely might want to split the stack into two separate stacks if that's possible in your design.

Let me know if you don't get an answer, I can ring up some resources at Avaya.

Cheers!

The technical answer is Stack Manager does not allow for more than 400 ports.

Well there's the technical answer.

Thanks Jon!

400 ports max is a limitation of the 5500 series code (8 switches x 48 ports=384). Since the 5600 series runs the same code as the 5500s, the limitation applies. Look for a future release of code to go beyond this.

The maximum # of switches in a stack is 8. Thus the 5600s could go up to 768 ports in a stack(8 switches x 98 ports). Today only the first 400 ports will work.

Also, be careful on your cascade cables. The 5600's look like carbon fiber, the 5500's look like chrome. The 5600's are rated for 72Gbps, the 5500's are NOT! When running 5600's in "pure" mode, you must use the carbon fiber looking cables. When running in "mixed" mode, it does not matter.

Cheers, Uncle John.
